Properties of matter

Properties of Matter

How do we tell different types of matter apart

How do we tell different types of matter apart?

Salt or sugar

Salt or Sugar?

What is a property

What is a property?

  • A distinctive attribute or quality of something

  • An observation

Two types of properties

Two Types of Properties

  • There are two types of properties:

    • Physical Properties

    • Chemical Properties

Physical properties

Physical Properties

  • Physical properties are properties that you can observe without changing the identity of the material.

  • For example: A rubber band is stretchy. If you stretch a rubber band, it is still a rubber band.

Physical properties1

Physical Properties

  • Physical properties are descriptive.

  • They include the appearance and behavior.

    • The appearance of the item is how it looks, feels, tastes, as well as any measurable characteristics like mass, volume, etc.

    • The behavior of an item is going to be how it reacts with certain other things. For instance, metals are usually attracted by magnets.

Physical properties2

Physical Properties

  • What are some physical properties of this honey?




Common physical properties

Common Physical Properties

  • Magnetic

  • Dense

  • Color

  • Size

  • Shape

Physical change

Physical Change

  • A change in the size, shape, or phase of matter is known as a physical change.

  • A physical change is one in which the basic identity of the objectdoes not change!

  • Another way to look at it is that a physical change is one which you can change back.

Common physical changes

Common Physical Changes

  • Physical changes change the appearance of a substance, but the chemical makeup does not change.

  • Examples of Physical Changes include:

    • Size

    • Shape

    • Phase (solid, liquid, gas)

    • Dissolving

Chemical properties

Chemical Properties

  • A characteristic that indicates it can undergo an chemical change.

Common chemical properties

Common Chemical Properties

  • Flammability

  • Reactivity

  • Rust (Oxidation)

Chemical properties1

Chemical Properties

  • What is a chemical property of this railroad spike?

Chemical change

Chemical Change

  • The changing of one substance into another.

  • New substances are produced because of the breaking of chemical bonds.


Detecting chemical change

Detecting Chemical Change

  • A new substance is ALWAYS produced in a chemical change.

Chemical changes

New substances are produced by the making and/or breaking of bonds.

Chemical Changes



  • There are five indicators that help us to know that a chemical change is taking place:

    • Unexpected Color Change

    • Energy Transfer

    • Precipitate Produced

    • Odor Produced

    • Gas Produced

1 unexpected color change

1. Unexpected Color Change

2 energy transfer

2. Energy Transfer

  • Endothermic (gets cold)

  • Exothermic (gets hot)

  • Sound produced

  • Light produced

3 precipitate produced

3. Precipitate Produced

  • Two liquids produce a solid

  • The solution sometimes looks cloudy or milky.

  • Solid falls to the bottom of the solution.

4 odor produced

4. Odor Produced

5 gas produced

5. Gas Produced
